BBF.RetrieveWPrime

Retrieve polynomials from W'.

Syntax

BBF.RetrieveWPrime():LIST

Description

Retrieve all polynomials from W'. Please note that in order to use this function you have to start the ApCoCoABBFServer.

Example

Use Z/(32003)[x, y, z],DegLex;
I:=Ideal(-4*x^2 + 1, -4*y^2 - 1, 5*z^2);
BBF.Init(I);
BBF.Steps(10);
-- After computation has finished:
BBF.RetrieveWPrime();

Output:
[x^3 - 8001x, x^2y - 8001y, x^2z - 8001z, xy^2 + 8001x, y^3 + 8001y, y^2z + 8001z, xz^2, yz^2, z^3]
